205	  By default, a media driver auto-selects all possible ancillary

207	  frontends, that are used by any of the supported devices.

210	  are strict constraints with regards to the kernel size,
211	  like on embedded systems.

213	  Use this option with care, as deselecting ancillary drivers which
214	  are, in fact, necessary will result in the lack of the needed
